an ecologically-based term centered on assessment of the impact of fire onthe ecology of the site.

This is complex thing because it is so qualitative.

Fire intensity-

energy produced

Fire severity-

direct effects of fire on the environment

Nancy French’s project:

To quantify the variability in biomass consumption in forested region of northern andwestern north America.

Remote sensing will be used to sample fire-disturbaed sites at broad spatial scales so thatthe full range of fires’ impact can be assessed.

Investigate the connection between spectral signature and biomas consumption bycomparing field and image data

Ground measurements and remote sensed measurements

Canadian project (Canadian Wildfire Fire Information system Emissions Team-CET):HAVE to deliver natioan estimates of carbon emissions (KYOTO protocol).. needsomething right away after a fire to show carbon emissions, so they are using remotesensing.. Remote sensing and the connection between fire emissions and carbon.

Canadian fire modeling: Interpreting “fire severity”. Doing a lot of prescribed burns, andfinding out that fuel consumption is reallycorrelated with pre-burn characteristics! CBM-CFS3 carbon pools. (Mike Apps, and Vernen?). BORFIRE model. FWI parameters andfuels data to calculate physical fire characteristics to get a fire emissions. Very similar toALFRESCO, but a bit more detail in pools within trees, but no shrubs.

NASA-NACP (Eric/Dave McGuire/Merritt’s work): “what is that stuff called duff”.Impacts of fire severity on these deep organic layers (mostly underlain with permafrost).TEM modeling with Dave. Carbon storage impacts, and carbon emissions. How much ispeatlands contributing to carbon emissions related to fire. What controls depth of burn?Especially in areas where short-term fire weather are not controlling the moisture to thesame degree. Quantify landscape, fire weather controls, and other controls on surfacefuel consumtion in the N. American boreal pealtnds and permafrosts. Developapproaches to imprive SFC in fire emissions and biogeochemical cyle models, generatetrace gas emissions estimtes from boreal fires for the years 1995-2006, determine howrecent increase in fire activity in the NABR region have influenced the terrestrial carbonbudget

What are the patterns of aboveground burn severity in the different forest/peatland typesthat burn?

What is the range of depth in burn. Really interested in the variability

How does dNBR represent fuel consumption?(CET-based on soil samples and OM depthmeasures, Verbyla, graduate student, Ted Schuur?), ESK/MT/NF will do this in AK in’05 and at ’95, and ’99 sites). Remote sensors think these AREN’T related… but weneed to have a couple of papers that SHOW this (so that people will stop telling us to usethe CBI all the time.

How does CBI represent burn severity/fuel consumption? (CET-

in 04 & 05, based onOM soil samples and OM depth measures. ESK/Mt?NF will do this in AK in 05 and at95 and 99, TH/UAF will do this for 2004 burns using TH pre-burn info). Maybe thisshould be a paper, where we pool all our data to test if there is a relationship between fuelconsumption and CBI. Then, if not, what can we create that will help us scale fuelconsumption.
